Yes! By using Probely's API, you are able to start a Partial Scan directly when you call the start scan endpoint, instead of needing to set it (permanently) on the target settings and then start a scan.
If you want to run Partial Scans through the API, you just need to send the reduced scope you want us to scan on your Start Scan request. Check our Developers documentation to know more!
